The Guardian newspaper has been running a series about the "Chemical
World" and I noticed a couple of items on Saturday
Isocyanates are linked to respiratory diseases such as asthma. So we're
considering super glue. If an adult like me hasn't got asthma by now,
then he never will; but maybe we should keep super glue well away from
children (we probably do anyway, but only to avoid the temptation of
junior applying glue to toilet seat .....) any maybe the family fridge
isn't the best place to store the stuff.
Methylene chloride reacts with haemoglobin to form carboxyhaemoglobin,
which stops blood cells carrying oxygen around the body. This is
actually the same as carbon monoxide poisoning. And methylene chloride
is the main constituent of Plastic Weld, which we all use on ABS
plastic. Apparently the safe concentration is 25 parts per million. I
doubt if methylene chloride is pernicious but I suggest we are all very
careful with it: no smoking, no sniffing; work in a ventilated room,
keep the cap on when not in use, keep away from children (who will be
affected by far lower concentrations) and use an alternative solvent
whenever possible. My personal preference is for methyl ethyl ketone.
Anyway happy modelling.
